The last post really informative and helpful for me too. I have Y rated tyres and only Michelin as only those tested on the car. I have Pirelli on my E39 and the club has a discount on them. Michelin owns ATS so often have a deal. I would never fit any ditchfinders ( cheap low grade) tyres on any car I own.

Dear Andy C,  Roadworthy means passing the MoT and not dropping below the MoT standard.  MoTs include checks on tyres and thank god for that as faults can develop in the inside walls that only putting the car on lift and going under can check.

The plate requires 205/60 R16 92 with the 92 being the load rating and all your preferences are 92s so I'll address your speed rating query and touch on your other points.
Speed rating:  It is amazing the range of speed ratings for your F30 320d efficient dynamics plus ('65 plate 48,000 miles) with the naff 16" wheels. H, V, W and Y!!!!!!!  So, 130, 149, 168 and 186mph in that order.

A possible explanation is that when first made that model was tested with wheels and tyres in all those sizes that actually had those capabilities.  Oh and the M is probably a get you home space saver rated to 81 when they tell you to keep below 50mph, but people forget and some folks are stupid and I saw one idiot try to smoke his.  Nankangs are only a £35 tyre, not as bad as some, but it is not a good idea having fantastic and not so great tyres on the same car even for 'normal' driving.

Cost vs value:  The Michelins may well be the originals, what do those date codes suggest, if 15/XX that was pretty good value. 

Speed rating:  Anyway, the pertinent question is how fast can your car actually go?  You do not give your reg or vin so if we go on your description https://www.ultimatespecs.com/car-specs/BMW/40038/BMW-F30-3-Series-Sedan-320d-EfficientDynamics-Edition.html suggests a Vmax of 143mph.  (Of course if the car has been chipped or tuned, but you say you won't be doing 130 so I take you at your word;)
If your manual says 143 is the top speed then being less than 149mph, a V-rated summer tyre is acceptable.  

It is also normal to accept a winter tyre one letter lower so an H rated winter.  ((Hence the next box down H M+S.  This is on the basis that winter tyres are used in winter when the road surfaces are much colder and thus heat buildup, the great enemy of tyres, is much less.))



Location and usage:  You say 'as it wet here' and I see you're in the UK, but there's a huge difference between London where it is +7oC heading for +2oC and Scotland where it has hit -9oC already according to AuntyB.  So, in one sentence; if you live in London and promise not to go out when it snows or is icy, get a summer tyre.  However, if you live or drive in Scotti-land or over 500ft think about winters to keep you moving regardless.

Aging:  You say the rears still have good tread on them, but some rubber degrades faster particularly if left in the sun.  What do the date codes say on the Nankang? [17/41 means 2017 week 41 and not that old should still be good for sedate driving but keep an eye on them.]  If the rubber looks crumbly or cracked, usually shows first on outside shoulders and side walls,  then plan to replace.

Bottom line £: At the end of the day it is only £18 between the Michelin * rated BMW approved tyre and your lowest option.  Expect the chains like ATS to charge a lot more, but to include fitting.  Though if money really is tight, go to Autopink-shop.co.uk for your Goodyears up front - now only £77.30ea (delivered) and expect to pay £15 a corner for fitting with hidden balancing.  Then get the rears done before you go on a big trip with your family.

Checking:  Indeed, old Russian saying: "Trust is good, but checking is better."  So, ask to keep the tyre labels.  Watch them fitting, balancing, adding air and pressure testing when fitted with car on ground.  Place the locking nut back in its cubby hole yourself.  Don't drive off without resetting the TPMS.  Drive cautiously for the first 100 miles and recheck the wheel nut torque and pressure when cold.

Hope this was informative.

Your mileage and performance may vary.  Always get advice and 3 quotes from reputable local tyre companies, if you pay them they are responsible, if you self-select it is down to you.  No liability accepted by me or BMWCCGB


Thanks Mostly Harmless, great post.

I tried to post a reply from my phone last night but it kept deleting the text!

I gathered it would be the MOT that decided whether it was roadworthy or not. It was MOT'd at BMW and no issues other than needing to keep an eye on the front left tyre, hence now is the time to replace. 

I am based in Cheshire, so about half way between London and Scotland! We tend to get a lot of rain, but not much on the snowfall front, just now and again. I manged to get away without winter tyres on the rear last year and was hoping to do the same again as i'm likely to be changing the car soon. Hence the reason for not wanting to go mad on tyres, but i'd never put cheap ass tyres on any car i own, even if getting rid.

I am now in a job where i am doing more miles, although tends to be shared with my boss and his A7. We have a big trip coming up so wanted to get some new rubber pretty sharpish as it has been very wet here recently. I was in a bind, so eneded up plumping for the Bridgestones after much deliberation and checking tyre reviews. 

I managed to get 2 fully fitted for £169 (10% discount code) from Kwik fit sowill let you know how i get on, much better value than the other options. It's not my preferred supplier but the boss has just had his 21" A7 tyres changed there and no complaints from him (fussy guy). No ATS here so checked, Kwik fit, National, Black Circles, Tyres on the drive and a couple of independents. 

Yes top speed is listed at 143mph, but i'm a pretty sensible driver and won't get anywhere near that. I figured i could probably put H's on as i won't being doing 130 either, but figured that was more for the Mud +snow tyres as suggested so i thought the V's covered it. 

If i keep the car any longer i will swap out the Nankangs for Bridgestones but i'll likely be changing car for another BMW or Merc, at which point i'll probably have it for 3 years so would think about winter tyres at that point. Looked for coding on the tyre, the only numbers that might make sense are 48/17? 

Now i need to find a thread about tyre wear indicators!

Cheers

I think you will also find it in your owners hand book, but door inner is good reference.
